Big Bag Machine

Large Volume Filling and Unloading System

Big Bag Machine

The term Big Bag Machine covers two main equipment groups related to Big Bags, which are large-sized flexible containers used for transporting and storing industrial raw materials (powder, granules, pellets, chemicals, etc.): Filling Machines and Unloading Systems.

Weighing System (Loadcell): All filling machines work gravimetrically (weight-based). There are precision load cells (Loadcells) integrated into the filling platform. In this way, fills between 500 kg and 2000 kg are carried out with high precision such as ±0.1% - ±1%.

Loading: The filled Big Bag is placed on the station with the help of a forklift or monorail crane integrated into the system and hung on the hooks of the frame.

Controlled Discharge: The discharge chute at the bottom of the bag is opened in a controlled manner with a special iris valve or similar cover mechanism. This allows adjustment of the discharge rate and minimization of dust emissions. Massage/Compression System: Encourages material flow by massaging the sides of the bag with pneumatic pistons.

Frequently Asked Questions

Questions and answers about Big Bag Machine

What is a big bag machine used for?+
Big bag (FIBC) machine performs automatic filling or unloading operations for large sacks with 500-2000 kg capacity. It is used for efficient and safe packaging of bulk materials or feeding them to the production line.
What is the weighing accuracy of the big bag filling system?+
Thanks to the integrated weighing system, filling can be done with ±500 gram accuracy. This accuracy meets commercial weighing requirements and prevents weighing disputes during customer delivery.
What materials can be filled into big bags?+
Plastic granules, powder chemicals, fertilisers, grain, sugar, cement and other bulk materials can be filled into big bags. Vibration and air evacuation system options are available depending on the flow characteristics of the material.
How is dust emission and environmental impact controlled?+
Botex System big bag systems work integrated with dust extraction and filtration units. This minimises dust dispersion during filling; worker health is protected and environmental compliance is achieved.
How are flow problems prevented in the big bag unloading system?+
Vibration table, pneumatic beater and flow aid devices prevent material blockage. These auxiliary systems are of critical importance especially for caked or moist materials.
